sounds like a bug.
I've never looked at /proc/stat.

I've seen this when CONFIG_PA20 is enabled but CONFIG_PARISC64 is not.
Don't know if that's your problem, but it's worth checking.

You don't need to enable CONFIG_PA20 in order to run a 32-bit kernel
on any system that will support 32-bit kernels (A500/L-class only
support 64-bit kernel).
